Missile experts were among the killed in the botched missile attack, which took place in al-Tayyar area of Majaz district in Saada province, Al Arabiya said.

However, a Houthi official at the rebel media denied the report, telling Xinhua on anonymity that the Saudi-led coalition warplanes targeted Kahlan military base in Saada overnight and killed two.

The Houthi declined to provide further details.

Houthi rebels had launched several missile attacks on Saudi border cities to retaliate airstrikes. Most of the missiles had been intercepted and destroyed in the air.

Saudi Arabia has been leading an Arab military coalition in Yemen against the Iran-backed Houthi militia since March 2015, in order to reinstate the exiled Yemeni government of President Abd-Rabbu Mansour Hadi.
